The Intenso External Hard Drive is very good, because your shiny casing of the optics and of the installed hard disk manufacturer (Western Digital) is more than satisfactory. When connecting to the PC it is recognized quickly and runs smoothly and quietly. The temperature remains fairly cool (about 32-38 ° C), as there are heated by some other external hard drive manufacturers such as Seagate with up to 50 ° C. I operate with USB 2.0, since I possess no newer system without any problems. I can only recommend the external hard drive that prefer what a lot of memory and a fair price / performance ratio. But you have to mention that Intenso installed other brands except WD and therefore I judge only those built from my HDD, so WD, then forgive 5 stars.
